A new rank card was introduced to the Extended Deck. This optional Courts rank is positioned between the Pawns and the Crowns and is composed of four cards with three suits each (just like the Pawns). The combinations of suits on these cards are the ones that don't appear on the regular deck.

These cards have not been released freely, so they're not really available at the moment unless you buy a decktet from P.D. Magnus (the designer).

More information from from P.D. Magnus can be found here: http://www.boardgamegeek.com/thread/390220

Here's the link: http://decktet.wikidot.com/local--files/introduction-to-the-decktet/decktet-vassal (from the wiki itself).

Right now it has 2 player sides (red and green) with their own hidden player hands plus the deck on the table with a discard pile.

I guess it's possible to save different setups for different games, but right now there are none. Still, it's not that hard to create a setup from scratch, as you can select cards from the deck manually, or shuffle and deal randomly.

I'm sure there are vassal features I've missed, and other things that could be used too, so please, feel free to comment, suggest, or post any tips or ideas.
